What is construction within a MS4?

A MS4 means a Municipal Separate Storm Sewer System, and relates to any stormwater conveyance system that discharges into State or Federal waters. Our NPDES permit requires that if small construction activities of one to five acres, and development or redevelopment of five or more acres within a MS4, then certain steps are taken to ensure that the construction does not pollute our waters. The City has its own requirements written in the Land Development Regulations.
